The Bold New Oris Big Crown Calibre 113 with Business Calendar

Oris has long defined itself as a maker of mechanical watches for “today’s world citizens”, with a clear commitment to function, value, robust engineering, supported by original looks. The new Big Crown Calibre 113 extends that philosophy by combining the brand’s historic pilot’s watch design with one of its most advanced hand-wound movements. Initially introduced in 2017 with the Artelier series, the in-house Calibre 113 belongs to the Oris 100 family and is distinguished by its 10-day power reserve, patented non-linear indicator, and a full business calendar. In 2025, for the first time, this calibre is housed inside the revamped Big Crown, the collection that has been a cornerstone of Oris design since 1938.

The Big Crown Calibre 113 features a 43mm stainless steel case, measuring 13.5mm in thickness with a lug-to-lug span of 50.5mm. It retains the utilitarian ergonomics of the original pilot’s watches, including the oversized screw-down crown. The 50m water-resistant case is topped with a domed sapphire crystal, anti-reflective on the inside, and features a sapphire display back secured with screws.

Oris opted for a bold palette to underscore the watch’s functional yet joyful spirit – even though it may be questionable in the context of a business calendar function (the colours don’t feel very business-like). The dial is mint green with contrasting pink sub-counters, and the indices and hands are filled with Super-LumiNova for readability. A 52-week calendar ring runs around the dial´s periphery, indicated by a central pointer hand with a pink tip. Day and date apertures sit at 12 o’clock and 6 o´clock, respectively, with small seconds at 9. 

The non-linear power reserve at 3 o’clock is designed to become more precise as the mainspring unwinds, with the final stretch of the scale expanded so the hand covers a wider arc, giving finer resolution as the watch approaches the end of its autonomy.

The watch owes part of its name to the underlying Oris Calibre 113, a hand-wound in-house movement with a 240-hour (10-day) power reserve from a single oversized barrel. In addition to hours, minutes, and small seconds, the movement incorporates a full business calendar, including date, day, month, and week of the year, all of which are adjusted via the single crown. The calibre beats at 21,600 vibrations/hour and includes a fine timing device with a stop-seconds feature.

The Big Crown Calibre 113 is worn on a multi-link stainless steel bracelet with a folding clasp developed in-house by Oris. Its taper and polished-brushed finish complement the case while emphasising everyday wearability.

The Oris Big Crown Calibre 113 is available from September 2025, priced at CHF 6,350. The warranty extends to five years with MyOris registration, covering both watch and movement.
